'Be it known that, I, Mouais lViLsoN, a-'eitcago,- in the county of (ook and' vState of Illinois, have invented new and useful ln provements in Non lare Rain-Shield Plates and Methods of ,Ma ing the Same, of which.

the following is a s eification.

This invention re ates toa .nonlglare rain shield plate and to the method nor manufacturing same and has for its primary --ohject the construction oa rain` shield that is positiv-ely nongl aring and which iscolored in such a manner that the coloring material is errnanent. f

,l n object of the invention is the novel manner-of arranging the projections .or corrugaticns on the surface of the plate so that there will bev .in interference between the light, rays and besides collected water will be drained in a direction'to drop from the ends of the plate instead ofthe longitutlina-l lower edge thereof.

A feature of the invention is the inexpensive method of making the glass plate .nonreflecting and which will give color rays that'. are very restful to the eyes.

lVith these and other objects in view the invention will be better. understood from the following detailed description vtaken in con-v nection with the accompanying drawing wherein Fig. l is a view looking,r at the top surface depth o the indentations.

of the plate. Y

F 1g. 2 is n view'looking at the under surfaceof the plate.

P ig. 3 is an enlarged sectional view before the coating of coloring material is applied.v Fig. 4 is a similar vie\v with the coating ap ilied.

gain referring to the drawing ilustrating one construction of my invention the' nu :neral 1 designates the top surface of the plf'iteor a vizor .While the numeral 2 designates the under Surface.

At the start I wish to call attenti-on to the fact that, the following description *.v'ill not flect in a direction to canse-nn interference' .betwecnthe rays. of reflection. ing the corrugations 3 as illustrated in the drawing an. .additional advantage is uccomplis'hed inasmuch as Water collecting on the plate will be conveyed towards the 'ends of the plate .Where'the same may be drained from the plate instead of' collecting on the longitudinal edged of the pla-te and theny dripping which interferes with the clear vision of the operator of .the automobile. 1

By :arrang- To color the glass in' a manner to absorb any light rays trying to pass through the glass plate or to color the lsame the glass isv colored in a manner that the color material is fixed and, therefore, cannot be removed. @ne of my many methods is to subject the under surface to the action of aY hlastrfofr I coarse Sand. until a relativeljy large numberof irregularly shaped indentations are formed and then increasing the number o f indentations and the depth thereof h v subfleetingr the under surface to a final action of a l'last of fine sand so that, theoretically speaking, the under surface i's shaped as s io-wn at 5 Fig. 3. The next step is to apply 4a coating of coloring material G to the under surface of the proper'consi-sten@v to .readilyr fion' into and become lodged the indentati'ons with the. resultthat the coating cannot be rubbed from the' surface and to 'coin-y pletciy remove the coloring material 'it .is

necessar f to wear the'surface to the glass the One manner of forniing this coating and applying saine is to mix-.a quantity of eolor- Y ino' niineralQai-id vari-)ish to the ro er conb i P sistency to enter theindentations'` .and itis and, therefore, I do notdesir'e to be limited' in any manner except. as set forth in the claims hereunto appended.

lHaving thus 'describediny invention ivha-t 1 claim is:

l. A non-glare rain shield plate .having one side roughenedand its other side im* pregnafed wit-lr a coloring material.

` its upper surface corru surface'of the plate'.

2. A non-glare, rain ahielrl plate constructed of 'gl-ass having one side formed with a series of projections to-cause an interfe'rer'xce` bet-Weenv the'light rays nstrikinthe plate, and a layer-of colbringn'lxateria upon the other side of the' glass havingporrtions embedded' betweenl said projections.

3. A -nonglare rainshield :plate having ted iin a direction to shed'water towards t fe ends .of the plate, and a colori-ng material applied to` the :un`

4. Anen-glare'rainfshield plate having it' vupper surface shaped to form aninterference between the light rays s-ti'kingthe:

. same, and its' under-"surface roughened; and s. coating of colored material .applied to the rou'g'hened surface..

5. A non-glare rain Shield plate Ahaving its upper surface corrugated and itfs under :surface acted upon to provide numerous ir- 'i1- 110 plat@ t? forni a of interfering light "x'fel'ee'tmg suaeesglsobjecting the under surf-ace of the plate 'li-rst .to' ascoar sand lalast and then to a fine sand blast, and apply-mg a eQ-tingof coloring A.material to the Vunder surface.

8. A method of orming'a -nomglareplate which consists in shaping the top surface of the plate to form a. series of interfering light reflecting surfaces, subjecting the nn@- -der surface of the plate, fir-St toa coarse sandblastand -thento 'a fine sand blast; and applying a coating of colori-ng material to the lunder surface consisting o f .a mineral and a. liquidof roper viscosity to freely flow into the in extatons form-ed 'by the sand blasts. a

` 9." A method of forming a-,nonvglare plate which consi-stein shaping the-top .'srface of theplaztteA to forma. series of interfering llight reflecting surfaces, subject-ing the under surface of the plate, finst to Aasociarse vsan-fl blast and then a fine sand blast `and applyino' a coating of coloring 'material to the millier Vsurface 'consisting of mixture of a-niinera-l. varnish and Vturp'entine ofthe proper consistenc to be readily sprayed into. the vindentatxons formed by the sand blasts.

In testimony whereof ailix .my lsigna'- tur'e.'
